Jessica is reportedly purchasing Sharon and Ozzy Osbourne's former mansion in the Hidden Valley neighbourhood of Los Angeles.
The 11,000 square foot mansion, which is more than double the size of her current Beverley Hills home, has six bedrooms and ten bathrooms, and a tidy list price of $13 million.
The purchase comes ahead of the arrival of her second child with fiancé Eric, with whom she already has 9 month old daughter Maxwell.Reports on US Weekly suggest the singer has already called in designers, and is looking to renovate the home to make it more family-friendly, including converting Sharon Osbourne's old wardrobe into a nursery for the second baby.
Jessica and Eric have put wedding plans on hold (again!) to focus on preparing their new mega-mansion for the arrival of baby number two.
